I found the issue with help from Richard and wanted to post what I found.

I went into my options. In Editor under File there is an area called "Associate Files". I noticed that the .SRC was not in the list (It was before the update). I added it and tried to open the *.SRC file and it worked correctly.

As did the drag and drop.

When I did the update to Ver14.0 the association lost the SRC extension. Once I added it to the list, all is well.
